What is the best theme for a podcast site?

i see mentions on the web to pod press, a plug in for wordpress sites. is this unauthorized? Do the sites support a podcasting blog? I would like people to be able to download the podcast into itunes. Is this possible on wordpress?

However, you can certainly add your podcasts to your WordPress.com site. There are a few ways to add audio to your blog, all of which are outlined here:http://en.support.wordpress.com/audio/

Regarding themes, all of our themes allow for the use of audio. If you'd like a few suggestions, would you mind letting me know what type of style you're looking for and how you would like to display your podcasts? I'd be happy to let you know a couple of layouts that might fit your needs!

Thanks, How much of a space upgrade do I need to do a series of 1/2 hour to 45 minute podcasts. I did purchase an upgrade but it is still not letting me upload w4m but i am assuming it takes time to take effect?

well, i just tried uploading it from my post. I clicked upload audio and then selected the file from my computer and then chose "none" so the media player would appear. I tried it using both uploaders. then the media player appeared on my post and when i clicked play, i just get the buffering. I will try to see how to upload the file into the library.
